Understanding Schema Markup

Schema markup is like a search engine’s reading guide for your website. Think of schema markup code as a highlighted pathway for Google to follow, letting it know the category of each text within a piece of content.
Unlike humans who immediately recognize an image, search engines need guidance to know what a page element is.
Key details are highlighted through the schema markup format, changing your site’s format preview within a search engine result page (SERP).
By helping Google understand specific information within your content, you provide quick information for your audience and organically boost your site’s relevancy.
Defining Schema Markup
Schema markup, also known as structured data, is the language a search engine uses to understand different web content.
Including the schema markup format within a page’s HTML code shows how specific information should be presented to a search engine.
Schema markup code is a standardized format that web admins use for varying content types. By using the same format depending on the content type, search engines understand the content better, pushing it to the top of the SERPs.
Popular examples are recipe search inquiries. For example, say you search for “fruit smoothies low calorie” on Google. The first results will have a picture, site link, user ratings, and ingredients.
Even if other links have the same information, the first links used schema markup to highlight their recipes.
Any user who sees them will want to view their link instead since it is visual, direct, and trusted by Google.
The Role of Schema Markup in SEO
Schema markup impacts SEO because search engines and users appreciate sites highlighting specific information.
Whenever a site page is published, search engines crawl it to understand the content and store it within its database.
If the web admin used schema markup for that page, the search engine should understand the content faster and format it correctly.
Schematic markup summarizes your site’s key details, helping users who want quick information. Even if the user has already acquired the specific needed information, they may still be enticed to read the entire content.
Schema markup reduces the bounce rate, or the percentage of people exiting the site after viewing, because users click your links knowing your content has what they need. Adding more information or fun facts benefits user experience.
Not every content type works with the schema markup format, but the code is generally flexible and understandable.
Google recognizes the effort and follows the format, organically bringing engagement and traffic to your site.
Schema Markup: A Semantic Vocabulary
Schema markup is one among many popular semantic SEO techniques that various sites use. But what exactly is semantic SEO?
Semantic SEO organically optimizes content for a topic rather than just a keyword or phrase. Here is a breakdown of its key terms:
  • Semantics: It is the study of meaning in language. For example, “soccer” and “football” have the same definition but are used differently in the US and UK.
  • Keyword: A short group of words that users search for about a specific topic. If people want to know about soccer, keyword examples would be “soccer teams.”
  • Keyword Research: Keyword research is finding the top keywords for specific topics. The “soccer teams” keyword is one of many soccer-related keywords.
Schema markup is part of semantic SEO because the format allows you to categorize keywords and relate them to one another. Your content shows in related searches even if it doesn’t contain specific keywords.
Using our last example, including soccer and football as keywords within your content’s HTML code lets people from the US or the UK find it.
Through keyword research, you can find additional keywords under soccer and football.
This way, your audience naturally grows, and more people find it on the SERPs.
Rather than focusing on a single specific keyword, schema markup focuses on the topic as a whole, broadening the audience range and enhancing your content.
The Collaboration Behind Schema.org
In the past, articles did not have a uniform content code format.
As more sites and articles spread online, many web admins had difficulty pushing their sites to the first page on SERPs because popular search engines had different formats.
After seeing this challenge, the three top search engines created a singular content format that worked across each search engine.
Google, Yahoo, and Bing launched schema.org on June 2, 2011, highlighting structured data formats that worked across their search engines.
The site remains widely used today by many web admins for various content types.
The simple yet straightforward HTML codes made it easier to input important details, and its multi-search engine support organically boosted many sites over time.

Significance of Schema Markup

While schema markup’s role in SEO is clear, it is not specifically required. Because of this, some web admins ignore it, preferring to focus on other codes.
However, investing that extra effort into schema markup can benefit sites for a long time.
By prioritizing the user experience over immediate high rankings, the page’s content remains highly relevant, increasing the boost in search rankings.
Whether you are a seasoned coding expert or a beginner, schema markup’s significant impact on your site makes it a worthy element to include.
Impact on User Experience
Whenever users search keywords on a search engine, they want results that show the necessary information within seconds.
Though the first few links share the same information, the top results or “rich results” with photos, reviews, and key details are what users will typically click on first.
The impact of UX on SEO is a key element that correlates with schema markup. UX, or user experience, is a big reason schema markup exists.
Schema markup positively impacts UX by offering quick, relevant information within the SERP preview. By immediately answering the search query, users appreciate the site’s extra effort, encouraging them to view it more.
Users are more likely to click on and return to sites that accurately give them the necessary details, are easy to navigate, and have supplementary information.
Even if these sites give key information, they also hold important details that are not shown in the SERP preview. Once users click it, the content’s understandable format improves UX.
Sites that prioritize UX and ensure the site is as simple yet detailed as possible have better engagement, boosting the chances of its pages appearing as rich results.
Influence on Search Rankings
Though including a schema markup HTML code within your site pages does not immediately guarantee high rankings, it significantly boosts its chances compared to other sites.
Placing structured data within your site improves its readability on search engines. As the search engine crawls faster through your site, it understands key details and how you want to format it.
For instance, you search for a Hollywood celebrity.
Though other sites may have the same information on the celebrity’s birthday or other personal details, sites using schema markup go further with pictures, categorized details, and a quick preview of their filmography.
Users are more likely to interact with these sites instead because they provide quick information. The increased interaction helps optimize for better ranking, relevancy, and authority.
If your site consistently uses schema markup formats for its content, the likelihood of more of your pages appearing first on SERPs increases, overall promoting your site.
Schema Markup and Local SEO
Local SEO is a digital marketing strategy where businesses aim to boost visibility across nearby geographical ranges.
We see local SEO in action when searching for a local company on Google or other search engines.
A highlighted box with their name, address, company number, customer reviews, and business website appears on the right side of the SERP.
Schema markup significantly boosts local SEO strategies by highlighting important information about these businesses.
Rather than making users browse through the site’s entire homepage, schema markup quickly shows relevant details, enhancing UX.
Using schema markup within your local SEO strategy boosts your site’s relevancy by giving users the needed details while enticing them to view the rest of your site.
Schema Markup and Rich Snippets Display
Google and other search engines extract key details from a page’s schema markup code. These details are then shown as rich snippets.
Rich snippets, or rich results, are information shown on SERPs that provide quick context besides a site’s blue link. It shows a quick preview of the essential information within a page, which boosts its visibility to users.
Rich snippet types differ depending on the content:
  • Review: This rich snippet type shows customer reviews in a 5/5 star format. This style is often used for pages about books, movies, recipes, or products.
  • Product: These rich snippets include customer star reviews, the product’s price, availability, and shipping information.
  • Recipe: These snippets show key ingredients for various food recipes, the time it takes to prepare, and user reviews.
  • Event: Event snippets show the location and date for specific events. For example, the event snippet can show a concert’s exact date, location, and time.
Users who view the rich snippet can immediately glimpse what your content provides. However, the rich snippet shows just enough information to encourage them to view the rest of your site for more details.
Using schema markup, you can quickly highlight these details depending on the rich snippet and content type. Not only do you make it easier for your audience to find information, but you simultaneously show your content’s accuracy.

Schema Markup Varieties

Rich snippets have various types, and schema markup is relatively flexible for many content types and topics.
Once you understand your content type, including schema markup to highlight key details, customer reviews, or prices becomes easier.
Product Markup
If you are an e-commerce business, using the product markup format is essential.
Product markups highlight the following key details:
  • Customer reviews
  • Price
  • Shipping information
  • Product sizes/variety
  • Image of a product preview
  • Availability
Most users do not have the time to browse your site for quick details.
Adding product markup formats into product pages quickly highlights what they need to know, allowing them to decide whether to buy the product.
Customer reviews are especially important here, too, since users will want to know whether a product is of high quality before buying.
By first including the customer review star rating, you quickly show your audience the product’s quality and value at a glance.
Review Markup
While product markups are more specific for e-commerce, review markups are a general format that shows how customers view a business, product, or service.
The main element within a review markup is the 5/5 star customer rating. Users check for these ratings to quickly understand the service or product’s value.
Article Markup
You may find a “Top Stories” segment underneath the search bar when searching for a specific news topic or article. This segment usually contains these details:
  • Featured photo
  • Article title
  • Publisher site name (ex. The New York Times)
  • Publishing date
Article markup is used to make these details appear immediately. They preview the article, encouraging users to click the link and learn more details.
Course Markup
The course markup format is important for education professionals. As the name suggests, a course markup details an educational course from a school or online platform.
These markups show the following details:
  • Course name
  • Featured image
  • The institution offering the course
  • Customer star reviews
  • Course price
  • Course duration
Using the course markup format, institutions or learning platforms can highlight specific courses and key details their audience needs.
Organization Markup
An organization markup gives Google and other search engines important information about a business.
These are common details within the organization markup:
  • Company name
  • Company logo
  • Company type
  • Business site
  • Short company description
  • Stock price
  • Headquarters
  • Founders
  • Contact details
  • Social media profiles
These details appear on the right side of a SERP in boxes called “knowledge panels.” By highlighting your company’s important details, your audience quickly finds a brief preview of necessary details.
Local Business Markup
The local business markup format is part of local SEO, highlighting key details about a nearby business. These details appear within knowledge panels when searching for a business’s name.
Though similar to an organization markup, the local business markup format has more comprehensive details:
  • Business name
  • Customer star rating reviews
  • Service options
  • Address
  • Operation hours
  • Contact details
  • Site for reservation
  • Busiest times during the day
  • Google Map directions
This format immediately shows a business’s value, hours, and contact details, helping many users who want to inquire or order from their site.
Event Markup
An event markup makes it easier for users to know details about specific events and where to get tickets.
The event markup highlights these details:
  • Event title
  • Event date
  • Location
  • Event duration
  • Main event site
  • Sites selling tickets for the event
  • Options to bookmark the event
Say you look up “concerts in Los Angeles.” Upon searching, you immediately see a segment at the top of the SERP highlighting all the concerts happening in Los Angeles.
Using the event markup format to promote your event greatly boosts visibility within your target audience while helping Google include the event at the top of the SERP.

Applying Schema Markup on Websites

If you are a coding novice, adding schema markup to your site’s content may feel daunting.
Fortunately, you do not need to be a coding expert to use schema markup.
Through quick and simple tools from Google and the following steps, anyone can include schema markup HTML codes and organically boost their site.
Google’s Structured Data Markup Helper
Depending on the main publishing site you use for your websites, such as Wix or WordPress, you may already have schema tools to edit.
However, one of the most straightforward tools that can help with Google SERP-friendliness is Google’s Structured Data Markup Helper.
This tool lets you choose schema types and tag data and edit the HTML to include the necessary information.
When you are ready to include schema markup code into your page, visit the Structured Data Markup Helper site and check the content details.
NOTE : Ensure the site’s content is already published so that key features work.
Choosing the Data Type
Pick one of the common data types listed within the tool. These are the data types to choose from:
  • Article
  • Events
  • Movies
  • Restaurants
  • Book Reviews
  • Job Postings
  • Products
  • Software Applications
  • Datasets
  • Local Businesses
  • Question & Answer Page
  • TV Episodes
Each option immediately gives you a format to fill in with custom details depending on your content.
Through this option, you do not need to manually code the schema format for a specific article type.
After choosing the data type, input your site’s URL or HTML code. Then, click the “Start Tagging” button.
Inserting the Markup on Your Page
After the tool loads up your site page, you will see your content page and a “Records” section on the right side of the screen. The records section shows the data type’s schema format with missing details.
To fill in these details, highlight a specific section you want to mark. If you are working on an article, the first part to highlight is the article’s title.
After highlighting the text, you will notice the following options appearing underneath it:
  • Name
  • Author
  • Date published
  • Image
  • Article section
  • Article body
  • URL
  • Publisher
  • Aggregate rating
For our article example, follow these steps:
  1. Choose the “Name” option. Once you choose it, the article’s title appears next to the “Name” text in the Records section.
  2. Highlight the article author’s name and choose the “Author” option.
  3. Highlight the publishing date and choose the “Date published” option.
  4. Using the options from the dropdown menu, continue to highlight the appropriate texts detailing the article section, body, URL, publisher, and rating.
  5. After all the details under “Records” are filled in, click “Generate HTML.”
  6. Check the generated HTML code and copy-paste it into your site’s HTML. They are in a JSON-LD format by default, but you can choose a Microdata format.
Once the code is on your site, it is time to check whether it works.
Verifying Your Schema Markup
We will use features from Google’s Rich Results tool for this example. This website helps test whether the schema markup shows appropriately on Google SERPs and spots any errors.
These steps highlight how to verify your schema markup on Rich Results:
1. Input the page URL or code snippet.
2. After the page loads, you will see the URL’s code on the left side. Any errors will appear on the right side.
3. Edit the code directly if there are formatting errors.
4. After fixing all the errors, click the “Run Test” button at the bottom right.
5. Do a site audit using free online tools. The site audit comprehensively shows each page’s performance based on SEO performance, crawl errors, link statuses, and other statistics.
6. Find the “Markup” section on the site audit page, then click “View details.”
7. You will see a percentage rating out of 100 that shows your markup score. Higher percentages mean fewer errors to fix.
8. To check additional errors affecting the score, follow these steps:
a. Click “Structured data items.”
b. Click “View all invalid items.”
c. Click entries within the “Affected fields” column. These details show the number of errors and fields that need editing.
After editing any errors, ensure you do the test again and monitor your site’s performance.
Addressing Errors in Schema Markup
Though you may correctly highlight all the necessary texts, errors may still appear within the code.
You may run into these common schema markup errors:
  • Missing or Incomplete Markup: This error occurs when specific texts are missing, preventing search engines from properly indexing the content.
  • Structured Data Mismatch: This error appears if the structured data within the schema markup code does not match the content text.
  • Incorrect Schema Type: Picking the wrong schema or data type leads to this error.
  • Improper Schema Markup Nesting: Schemas are “nested” or related to one another, and this error appears if two schema texts are incorrectly connected.
  • Multiple Schema Markups: Placing conflicting or multiple schemas into a single page causes errors and inconsistencies in the search results.
The first step to addressing schema markup errors is understanding the error type. Once you have identified an error, follow these steps:
  1. Use Structured Data Testing or Rich Results tools to check if other errors appear in your code.
  2. Review the content and check that you highlighted the correct data for every schema markup element.
  3. Check that you picked the right data type during the first step of the Structured Data Testing tool.
  4. Review the schema markup code to check that all details are correctly nested or related to one another.
  5. Ensure the code follows a logical format.
  6. If you find multiple schemas, combine them to avoid inconsistencies and confusion.
Though it may be time-consuming, ensuring the code is error-free boosts your site overall.

Advanced Schema Markup Topics

Sometimes, content has mixed data types or requires additional information beyond the standard schema markup.
When such situations happen, advanced schema markup practices can help more experienced coders ensure the site still gains relevancy.
From noting different content versions to using artificial intelligence, these advanced schema markup topics are crucial for anyone wanting to make the most out of schema.
Machine-Readable Information Versions
Machine-readable information versions involve specifying different versions of structured data within your schema markup.
This process, known as “versioning,” is often used for websites with continuously updated articles.
Adding these details is important for noting whether information has changed or is no longer relevant for a specific topic. By noting the updated version, search engines will show the latest version rather than an older one.
Most sites use three types of versions, each representing different levels of change:
  • Major version
  • Minor version
  • Patch version
An example of versioning is when a game’s publisher website publishes a “patch notes” page detailing error fixes within a game.
Search engines and users are immediately notified of changes by detailing that it’s a patch version.
Checking that the content and the schema markup code are updated with the latest information ensures that users and search engines find the most accurate information within your content.
Utilizing the Schema.org Vocabulary
Schema.org has various tools and terms that are crucial for anyone utilizing schema markup formats. However, these advanced terms may feel confusing if you have little previous coding experience.
The key terms are “types,” “properties,” and “entities.” Schema.org has over 800 types, almost 1,500 properties, and extensions for various content topics.
Here are important definitions to remember:
  • Types: Types organize entities under specific categories. Types are used to define properties or terms used to define an entity and how they are linked to other entities.
  • Property: Properties are attributes or characteristics that give additional details about an entity and its relationship with other entities.
  • Entity: An entity is a unique and distinguishable thing or idea. Entities must have unique attributes and exist in relation to other entities or topics.
Types require the following information:
  • The type’s name
  • Where the type fits in schema.org’s data hierarchy
  • Type definition
  • Description of the type’s properties
  • Property types or related types that the property is connected to.
Your code follows a logical flow of information by correctly relating all entities, types, and properties to schema.org’s data hierarchy.
If the search engine can follow an organized code, the schema markup functions properly, reducing the time spent fixing errors.
Expanding Schema.org
Though schema.org supports various data types, expanding the website means you will go beyond its given vocabulary to cover other topics, domains, and industries.
For example, say your content is focused on sustainable farming practices. Though schema.org provides a markup about farming, it could be limited, stopping you from including additional, yet vital, information about the topic.
Expanding from the schema.org vocabulary on agriculture means introducing new types and properties related to the topic. Examples include a new type called “SustainableFarm” or a new property such as “EnvironmentalImpact.”
These extensions will allow you to provide new information without breaking your schema markup code. Users appreciate the added details, which boosts your site’s authority.
Schema Markup and AI
Artificial intelligence (AI) works well with many parts of SEO, and schema markup is no exception.
The speed at which AI understands and generates search queries increases through the details provided by schema markup.
Here are some of the ways that schema markup and AI can work together:
  • AI algorithms use information from the schema markup to generate rich snippets.
  • AI-powered search engines use machine learning techniques to better understand schema markup codes, increasing the amount of content the engine indexes.
  • Using semantic signals with different entities, schema markup gives additional context to AI, which helps deliver more results to a broader audience range.
  • AI content uses schema markup elements to generate content based on a user query.
  • AI uses schema markup to generate personalized search results that fit every user’s search preference and behavior.
There are many benefits to combining schema markup and AI, and each one improves user experience and site performance.

Schema Markup Best Practices

Whether you use advanced schema tools or prefer simpler methods, the best schema markup practices ensure the process remains smooth and organized.
Utilizing Necessary Schemas
Ensure you pick the right schema type before generating the code.
For example, if the content is an article, check that you chose “Article” on a schema markup tool to get the right format.
Embracing More Markups
The variety of markup formats opens new opportunities for content to thrive within different search queries.
Rather than only choosing a general markup format like an article for all your content, you can explore other markups, such as “Recipe” or “Book.”
By embracing more markup formats and experimenting with different content types related to your niche, you increase the chances of your site appearing first on SERPs.
Frequently Used Schemas
Here are some common schema types and how best to use them:
  • Organization Schema: If you use this type, check that all contact details, addresses, and social media profiles are accurate.
  • BreadcrumbList Schema: This schema type acts as a navigational resource, showing a site’s content structure. Ensure each element fits within a proper structural hierarchy.
  • Article Schema: Include the author’s name, headline, publishing date, and article body. Check that other elements, like photos, are properly coded.
  • Product Schema: Include customer reviews, description, price, and availability. Consider additional details like sizing or color options.
  • LocalBusiness Schema: Include operational hours, current address, contact details, and geographic coordinates.
  • FAQPage Schema: To properly mark frequently asked questions in an article, ensure all the details are accurate and answer all listed questions.
By properly using each schema type, the quality of the content improves for both the user and the search engine ranking.
Avoiding Common Schema Markup Mistakes
Avoiding schema markup mistakes involves regularly checking the code and ensuring all entities, details, and properties are in the correct order.
These are a few ways to avoid schema markup mistakes:
  • Understand and study schema.org guidelines to properly implement each schema type.
  • Test the markup whenever you change any parts of the code to ensure errors are quickly found.
  • Do not choose schema markup types that are irrelevant to your content.
  • Study Google or other search engine guidelines to know what they permit.
  • Keep the schema markup format consistent throughout your site.
  • Do not overuse a markup format for every element. Focus on the main content and key details to highlight.
  • Check schema.org regularly for possible updates that might affect your current code. Update the code if any changes occur.
  • Check that all the information is accurate before highlighting it.
  • Regularly test the code.
Practicing these methods regularly makes spotting errors and reducing them simpler.
